Title: Induction heating device for can drink
Inventor: FURUTA TOSHIHISA
IPC: G07F9/10
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To heat a can drink up to a prescribed temperature in a short time without heating locally a cemented can, etc., having an electrically insulated junction by preparing an elliptic or rectangular shaped heating coil that is curved along the outer circumference surface of the can and increasing the longitudinal length of the coil compared with the axial direction length of the can. SOLUTION: A heating coil 1 has an elliptic or rectangular shaped form and is curved along the cylindrical wall of a can 50. Then the length L1 (outer diameter) and L2 (inner diameter) set in the longitudinal direction (longer axis direction of ellipse) of the coil 1 are increased compared with the axial direction length L0 of the can 50. As a result, the eddy current is primarily generated along the can wall set in parallel to the can axis. Thus, the heating is suppressed at both end parts of the can 50 and the abnormal heating is eliminated even though the can so has the junctions at its both end parts.

Title: Sound stopping device for piano
Inventor: KIHARA TSUTOMU
IPC: G10H1/34
Filed: 1994-05-31
Abstract: PURPOSE:To obtain the sound stopping device for the piano which interferes with none of other parts of the piano and can easily be arranged and moved even when the movement quantity of a stop rail is made large by using a rotating mechanism. CONSTITUTION:When a player presses down a key, a damper lever 10 swings clockwise from the solid-line state against the energizing force of a damper lever spring 18 as shown by the broken line, so a damper lever wire 12 crosses the swing axis of the stop rail 20 to enter the space sandwiched by an arm 24. When, however, the damper lever wire 12 enters this space, the stop rail 20 only swings between the sound stopping position shown by the solid line and the sounding position shown by the broken line, so the damper lever wire 12 never interferes with the stop rail 20. Therefore, even when the movement quantity is increased by using the rotating mechanism as a simple mechanism, there is no interference with other parts of the piano and the arrangement and movement of the stop rail 20 are facilitated.

Abstract: PURPOSE:To reduce the cost of production in the process for forming the light shielding vanes for cameras which are formed by laminating prepreg sheets impregnated with a matrix resin in unidirectionally oriented carbon fibers, then heating and pressurizing the laminated sheets. CONSTITUTION:A resin film 20 coated with a light shieldable and/or lubricative coating material 20a is laminated on at least one surface of a laminate and the laminated sheets and film are simultaneously heated and pressurized at the time of laminating the prepreg sheets 2(3) formed by impregnating the matrix resin 6(8) into the unidirectionally oriented carbon fibers 5(7). Since the resin film 20 coated with such coating material is thereby tightly adhered to the laminate, the stage for separately applying the coating material on the surfaces of the vanes is saved and the cost of the production is reduced. In addition, the direction of the carbon fibers 7 of the prepreg sheets 3 of the intermediate layers is set in the transverse direction of the vanes and Panne family which are inferior in elasticity but are light in weight and inexpensive are used for the carbon fibers 7 by which the cost of production is further reduced and the weight is reduced while the sufficient rigidity is retained.
